Learn more by watching our NLS 30048 | Standard Deep Mounting Block 34mm | White video.
The NLS 30048 is a 34mm deep surface-mount mounting block, moulded in white and sized to suit standard 84mm-centre wall plates. The 30048 lifts power points, switches, and similar accessories clear of brick, sheet steel, or corrugated surfaces that cannot accommodate a flush installation. It measures 123 x 81mm and is supplied with two wall-plate mounting screws.
Surface installs on solid brick, sheet steel, or corrugated walls leave no cavity for the cable terminations behind a power point or switch. The NLS 30048 adds 34mm of internal depth, providing room to house conductor loops and bulky terminations without forcing the wall plate to sit proud. Its 84mm mounting centres match standard faceplates, so the accessory lands square for a neat, factory-fit finish.
For contractors fitting out sheds, garages, or rendered masonry, the 30048 is a low-cost backing block that holds position and fixes off quickly. The one-piece moulding stays square beneath the faceplate and accepts the two supplied screws directly into the substrate. At this price point, electricians routinely order the 30048 by the carton and keep a supply on the van for surface installations and retrofit work.
The NLS 30048 is not rated for wet or weather-exposed locations and carries no IP rating, so it should not be installed outdoors or in unprotected damp areas. It is a surface block intended for dry interior and protected positions, not a sealed or weatherproof enclosure.
Verified Sparky Direct customer reviews: NLS 30048 Standard Deep Mounting Block 34mm (30048)
"well made mounting block" — Terry
"Very Happy did exactly what I needed it to do" — Gary
"Great product for the price" — Scott
(30048)
The NLS 30048 ships with two wall-plate mounting screws for fixing the faceplate to the block. Fixings for securing the block to the wall depend on the substrate, so use masonry plug-and-screw for brick and self-drillers for steel, matched to the surface behind it.
Standard-size power points and switches with 84mm mounting centres fit the 30048, which covers most common Australian GPOs and light switches across brands. Confirm the faceplate being fitted uses the standard 84mm centre pattern before ordering.
The NLS 30048 is 34mm deep, giving more internal room than a shallow block to house cable loops, terminations, and deeper-bodied fittings such as dimmers or timers. The added depth also helps conductors sit within the bend radius the wiring rules require.
Surface mounting an accessory on a block is compliant under AS/NZS 3000:2018 when correctly specified, with the block depth chosen to suit the cable bend radius. All connection work must be carried out by a licensed electrician.
The 30048 carries no IP rating and is not designed for wet or weather-exposed positions. Keep it to dry interior and protected locations such as living spaces, garages, and workshops. Outdoor or damp installs need a weatherproof enclosure rated for that exposure.
The mounting block uses a one-piece moulded body that holds its shape under the faceplate and stays square when the accessory is screwed down. It is a plastic surface block, so it supports a standard wall plate and its wiring rather than any structural load.
The NLS 30048 is available online from Sparky Direct, with Australia-wide delivery to any state or territory including regional areas. Sparky Direct is an Australian electrical wholesaler established in 2005, supplying more than 500,000 customers with transparent trade pricing.
